Clinical Observation of Blood Pressure Changes During Spinal Anesthesia / 대한마취과학회지

ABSTRACT

In an attempt to observe the influence of the spinal anesthesia on the systolic blood pressure, 350 cases of the spinal anesthesia ranging from 16 to 60 years of age were analyzed. The spinal anesthetics in this study was hyperbaric solution of 0.5% tetracaine in 6 or 10% D/W. The 350 cases were put into 4 groups by their preanesthetic systolic blood pressure and by post anesthetic dermatome of sensory block, and then the alteration of blood pressure in systolic of each group was studied. The results obtained are as follows. 1) The maximal fall of blood pressure was seen at 10 min. after spinal anesthesia. 2) Of the groups of the same sensory block dermatome, the fall of the more prominent in the higher initial systolic blood pressure group. 3) Of the groups of the same initial systolic blood pressure, the fall of was more prominent in the higher sensory block dermatome group. 4) The most prominent fall of the systolic blood pressure during spinal anesthesia was seen on the highest sensory block dermatome and initial systolic blood pressure.
